Application lcd March 6, 1915.

l'of 'which Vthe following is a full, true, and

` complete specification.

The objectof .my irivention is to provide l an instrument for use as a medical syringe, adapted to discharge the liquid medicament from collapsible, sealedcontainers or tubes representing individual chargesor doses in unit package form. The device accordingly comprisesy a holder for the' tube and means .5 for collapsing the latter' to eject its con- -.t .ents-mechan1sm being preferably also pro- Yide for puncturing the tube just before use, and for` properly assembling the parts or use With hypodermicneedles. In the 2am preferred con'stru'ction the 'device comprises a pairof squeezing members with means for holding the collapsible tube and nozzle or needle disposed between them; but many other 'dii'erent embodiments are practicable,

for example such as that shown in my German VPatent No. 280,192 of March 28, 1914, wherein the tube is collapsed by a rolling action, .and it is to be understood that in 'cer tain instances all of the instrumentalities .30 mentioned -need not be employed in conjunction, or that others may be added or substi- `tuted, depending upon the particular purposein View, and that I do not limit myself to the particular application of the principles and mechanism of the invention indicated above. Various features and advalr4 .tages will become apparent, as the specification proceeds and a're more especially pointed out in the claims appended hereto. In the accompanying drawings forming a part hereof:

. Thel fluid to be' discharged or injected is to be supplied inclos 'ad unit containers l2, 75 of collapsible material suchas'tin or leadir a suitable alloy which liter using' are thrown away, being thus prop arly designated as single service containers A' filled tube -s shown in Figs. 1 to 4, indzthe collapsed con- 3U dition produced by ;he lateral squeezing means which I prefer 'to employ is illustrated in Fig. 9. The tubes have a folded or crimped rear seaurll ind a threaded nozzle portieri 14 at the op )ositc end, the latter 35 being closed by a slightly concaved wall 15. constituting Ian integral or seli`-contained seal.

The holder for the tibe consists in this in-' stanceof .a central bar 16, having suitable means for receiving the tube and holding ib in proper relation to the squeezing members.

' The said means comprise .a socket '1T on the.

forward, end of the bar having an internal screw-thread 18 for .the insertion of the threaded nozzle, and .i recess or slot 19 at the rearward portion of the bar to receive` the flattened seam end of the tube. The socket 17 is pivotally mounted on forward end of the bar as prcscrly described and the said-slot 19 is formed,l in the main hinge support or pintle 20 of the squeezing@ members, which pintlc projects upward atl right angles from .the iear end ofthe holder bar, being secure thereto. in the 'manner clearly shown in 1g. 7. i

The squeezing meair; comprise two angularlv-clo'sing lateral members '21, which opcrate' in a plane offset from, and parallel to,

the intermediateholder ineinber 16.' At their rear ends these members are 'hinged on the pintle as shown in Figs. G and 7, by the confinement of their curved extremities 22 within 'the annular space provided between the pintle 20 and an exterior sleeve or caspose the springs may be anchored each at' one end to the' piiitleg with their opposite ends bearing outwardly against lugs 25 on the squeezing members and their iiiteriiie- `diate coiled' portions Qipressing inwardly "against opposite sides of the* Iiolder bar.

The degree of separation o f the squeezing members is limited by stop engagement of their outer sides with the edges of the sleeve The said members may o f. course be formed in various ways. In the present case they are built up of'several united pieces, one piece 27 being H at so as to afford aplane face for pressing against the tube container and the hinge portion 22 being formed at the rear end of this part. The

other or outc r` piece 28 is formed with `a .pressed rib' 29 for strength and carries' a.

finger button 30 at its forward end, asshown lybeiir'g also curved to f o'rin inwardlyfacingcavities 46 forward of the 'squeezing faces and as shownl in Figs. 1 and 2. Thesecavities accommodate the socket A 17 above referred to andcertain other parts when the squeezin .members are closed to- .i getherupon theco lapsed tube.

The socket '17. is swiveled in a sleeve 33,

' g 'wherein it is rotatably confined by a kniirled head 35 on one .end of the sleeve and a flange at its other end, so that it may be grasped by the said knurled head and rotated on its tube is indicated in Fi own axis. The said sleeve is` provided vwith a l'ug or'arni 36 by which it is pivoted, at 32, to the end of the bar 16 so that it can be turned, iin such transverse axisto the position indicated in Fig. A2.. In this posi' tion the ci'illai'isible .tube 12 can either be screwed into it',- or it can be screwed Aonto the tube. and then by swinging the sie-eye oii its -pivot 32 the seamed end of the tube can be readily .introduced into the slot 19 above refer-red to. A notch 37 in the pivot lug 56 is adapted to be ei'igaged by thegwali of a notched tui'n liuttori38 pivoted on the bottom of the holder bar, so that the' tube will be securely confined in position between the squeezer members. This position of the 1 and 3 a'nd also by the dotted lines of Fig. 2.

Thep'uncturing of the forward end .of the eontainers preferably done by 'a rearward extension 39 of a nozzle or needle 40,

means being provided for assembling the puncturing device is introduced from the' front.' it is unnecessary to remove the puncturing screw, which may be accordingly pro-I vided with an enlargement 45, which guards against possible loss by preventing disen- .eoncaved end wall 15 of the said tube and the interior of the latter is thereby placedin communication with the needle. ManifestlyI the needle `might be provided with a screw-j 'thread to engage directly with the screwthread in the forward part of the socket,

for obvious reasons. The head -of thepunc turing screw is also knurled as indicated to be noted, that the screw is threaded in the reverse direction to the threads vvhiclreon- `-lgfageinent from the socket 17. 'By screwing but thel use of a separate means is prefeijred'j ,E provide a secure grip thereon and 'it is to nectthe tube, to the socket 17 so that.' the" A operation of the said screw does no'ttend to loosen the )o'int or connection, previously made. The direction of -thebayvoi'iet slot' 42 is also the reverse of thethr'eail f'ofthe'l'u' puncturing screw, so that theio'peiation of i the latter does not tend to .(,lisengage the needle therefrom or tuin it to itsl position for removal. In, tli'e case illustrated the tubes are screwed .into the socket with a left hand thread, the puncturiiigr screw is right hand andthe l'iayonet slot is left h and, this relationship being important for the. reasons" noted.

-ln order to enable the device to be used with ordinary standard needles one or more" adapter's n'iay lie included as part of the equipment. These adapters "are hollow puiictiiri'ngr elements adapted to be contaiued in the screw 41 and to be''secii'reh v thereto 1n the saine manner as the needle 40.l 'i

and are so formed at their 'forward endsas to he capable of being lloiiited with ordiuairy needles.l

-tight driving fit with the soft metal wall l5 i Fig. l0 shows an adapter fli" A designed to receive a. taper or coiled 'needle las of the tubewhen the latter is 'piinctureih so that'the liquid is not Iallowed to'escape' into the interior of the socket or to touch any iiortion of the instrument before entering the adapter or thel needle, as the case may be.

When the needlef40, or .the needle and aula'iter as the ease may be, has been secured to tlie puncturing screw and the. latter has been screwed home to puncturey the unit dose-containin tube the nozzle may' then be introduced into the place Where the injection fis to be deposited, and the squeezer members 27-28 ere then pressed together,

. which discharges the entire contents of the tube"through the nozzle, lea-ving thetube collapsed and completely evacuated as 1n llieated in Fig. 9, l l

From the foregoing description, the operation Iand advantages .of the device will be apparent. The system of unit .sealed park- 4 tentsfto be discharged. Manifestly the leach -ing feature of they invention is the revision of a vmechuniceil injection `device avlng a lgw"sinle-'service' reservoir, whereby the uncer;

ties and dimgers of ordinary Syringes and the necessity forjsterilizing the rcsec voire after and before use are avoided. In the present invention only the needle or the adapter `and needle require sterilizing, subJect to repeated use.
